The Currie Rock Crawler II rear bumper for 1987-2006 Jeep YJ, TJ Wranglers, and the LJ Unlimited is the first bumper designed specifically with rock crawling in mind. The Rock Crawler II was developed by Currie and has been tested in numerous competition events on our own vehicles. All angles of this bumper are designed to provide maximum approach angle clearance. This unit is 54" wide and is fabricated out of 1/4" plate steel and black powder coated for durability, and features a 2" receiver that accepts the Currie tow hook. They are easily mounted and are a direct replacement for the stock Jeep bumpers.
